thanks for the excellent example (and I am using Tk now!) but I don't really need all those unecessary widgets on the screen (like stdout).

I just need something like (pseudocode) 

system(command) until (done or user_aborted_with_keypress)
quit if done;
goto next step if user hit 'N'
goto previous step if user hit 'P'

I could use Tk if it would be more sparse on the interface tho...

thanks!
